I don't like Xui Hua, this system. I'm not sure if it's intentionally messing up or not; nevertheless, its actions, if its pettiness or stupidy continues, will put the MC in further danger. Systems are supposed to help their hosts, and with ML's current blackening level, even one mistake can turn anything and everything into a very dire situation. Poor MC, he's just doing his job because he wants to live again. But then again, maybe it's for the story's comedic factor... still, this kind of "mistake" pis*** me off so much.
